Dear All -
This question was answered in September this year on the list.
This (unhelpful) error message arises when SAC cannot decode a number in a pole-zero file. Suggest that you look carefully at its contents to see whether any non-printing characters are present, tabs used rather than spaces, etc. Also make sure you're typing the correct file name on the TRANSFER command.

Hi,
I am trying to remove the instrument response from the data using transfer function as shown below:
SAC> r 2010.332.14.48.FS12.BHZ
SAC> rmean
SAC> transfer from polezero s FS12_ZVBB.zp
ERROR 1:
My pole-zero file for station FS12 is
CONSTANT 3.605e+17
ZEROS 2
0.00E+00 0.00E+00
0.00E+00 0.00E+00
POLES 5
-3.701E-02 3.701E-02
-3.701E-02 -3.701E-02
-1.131E+03 0.000E+00
-1.005E+03 0.000E+00
-5.027E+02 0.000E+00
I am unable to understand why this error is appearing. Though I am following the same format for pole-zero files for rest of the stations in my network but SAC is having problem only with few stations. I have double checked the response files from the IRIS, DMC website for this station (FS12) and all the values are exactly same as it is in my pole-zero file. I would really appreciate your advice.
Thanks
